So I am usually so regular. My cycle comes every 28 days and I always ovulate on day 13 or 14. I have had 2 periods since my last m/c and both were totally normal. This past month I am pretty sure I got a + opk on day 13 as usual. On day 20 I had strange cramping almost identical to ovulation pains. I took an opk just for fun and it was definitely +. What the heck??? So I was expecting AF on day 28 and now I am 4 days late. I took a hpt and it is negative. I have been having cramps all week. What the heck is going on? I have never been late before. I am so frustrated. I am supposed to have all these tests done on day 2 of my period but it wont come!!! ARGH!!! I am going to call my RE tomorrow to see what the heck is wrong with me. Why now?? I am hoping he will give me something to make my period come. Do any of you know what could be wrong with me now? I am so scared that maybe I am now starting menopause or something and I am not even 33 yet

Any ideas of what this could be??? Thanks
